+ *
+ * Supported hardware:
+ *      Tested on SOC sbus card bought with SS1000 in Linux running on SS5 and Ultra1. 
+ *      For SOC sbus cards, you have to make sure your FCode is 1.52 or later.
+ *      If you have older FCode, you should try to upgrade or get SOC microcode from Sun
+ *      (the microcode is present in Solaris soc driver as well). In that case you need
+ *      to #define HAVE_SOC_UCODE and format the microcode into soc_asm.c. For the exact
+ *      format mail me and I will tell you. I cannot offer you the actual microcode though,
+ *      unless Sun confirms they don't mind.
